So, what's the deal? Is Rob celebrating the fact that at 29, he's still a little boy at heart? Blac Chyna's Instagram reveals that the trip might have been more about her other main man - her son, who was with them enjoying the day and exploring the LEGO sculptures.
Just to remind everone in case the awkwardness has started to settle in - Tyga is the father of Blac Chyna's son. So, while Rob Kardashian is playing the part of pseudo-stepparent, his sister Kylie Jenner is doing the same thing when King Cairo is with his dad. Awwwwkwaaaaard.
